Technical Advantages
- non-invasive: No need to modify the WeChat client or protocol to avoid the risk of blocking numbers
- cross-platform compatibility: Based on image recognition, theoretically supports all operating systems
- Flexible Expansion: Interchangeable YOLO/OCR models to adapt to interface changes
Existing limitations
- resolution dependency: Decreased recognition accuracy at low resolution
- Window Status Requirements: Need to keep the microsoft window active and unobstructed
- version restriction: Currently only adapted to WeChat 4.0, the new version of the interface requires model retraining
Optimization Recommendations
The use of high-precision commercial OCR interface to improve the text recognition rate, combined with the element coordinate caching mechanism to reduce the overhead of repeated recognition, the complex scene is recommended to work with image pre-processing technology.
